Nor145 is well suited for measurement of building acoustics in the form of measuring reverberation time and sound insulation either with a single channel or dual channels. Measurements are made in one-third octave bands. The theory behind Building Acoustics measurements may be found below:

Building Acoustics theory.

There are different Setup menus available in order to adjust the Building Acoustics parameters. Please see the link below for further information:

Building Acoustics setup

There are two display modes to simplify navigation in Building Acoustics.

The Measure (or SPL/Idle) mode appears after starting the instrument or changing into Building Acoustics mode. This is the mode where measurements are taken, contrary to Project (or Data) mode where the accepted measurements and rating results are presented.

The soft key in the lower left corner lets you switch between these two display modes.
